Unfortunately, the front end results in an infinite redirect loop. The ONLY way I can get it to stop is to change the "Site Address (URL)" to match the "WordPress Address (URL)", which is http://myaccount.host.com.

Ultimately, I need this to work EXACTLY as before, where a customer views our blog through http://www.company.com/blog, but the blog needs to be in the root directory of my hosting account instead of the /blog subdirectory.

I hope that was reasonably clear - please help!

PS - I haven't even starting setting up multisite yet - all these problems are on a simple installation.
